In the process of precision parts manufacturing, not only material selection and design are concerned, but also the principle of parts processing should be understood. What are the principles of machining? The following parts processing manufacturer Xiaobian to tell you:

1, the benchmark first

First processing datum, parts in the process of mechanical processing, as the positioning of the appearance of the benchmark should be processed first, in order to provide a fine basis for the processing of the following process as soon as possible.

2. Divide the processing stage

Machining quality to have a high appearance, processing surface can be generally divided into rough machining, semi-finishing and finishing three stages. Mainly in order to ensure the quality of processing, conducive to scientific application of equipment, facilitate the arrangement of heat treatment procedures, and facilitate the discovery of blank defects.

3. Face before hole

For the box, bracket and connecting rod and other parts should be processed before processing the surface of the hole. In this way, the plane positioning can be used to process the hole, to ensure the precision of the position of the plane and the hole, and to bring advantages to the processing of the plane hole.

4, finishing processing

The finishing of the main surface, such as grinding, honing, grinding, rolling, etc., should be placed at the end of the process line. The principle of drawing up parts processing process route, the formulation of parts processing process regulations, can be roughly divided into two links. First of all, the development of parts processing process route, and then determine the size of each process, equipment and process equipment used and cutting specifications, time quotas, etc.

In machining, error is inevitable, but the error should be within the allowable range. CNC machining manufacturers think that through error analysis, master the basic law of its change, so as to take corresponding measures to reduce the machining error, improve the machining accuracy.
